UPPP : Uvulopalatophyrngoplasty
The surgery consists of tissue rearrangement at the uvula, palate and throat walls in order to increase the airway size and decrease tissue collapse.
Initially described several decades ago, this technique has been refined with several modifications to minimize possible long-term side effects such as swallowing problems, voice changes or permanent feeling of a foreign body in the throat. However these side effects, while rare, may still occur.(Authorized Standford health care)
